VF-2 on 'other' camera's...

After waiting for the XZ-2's arrival for some months, but seeing the other options now available, I'm toying with getting the Nikon P7700 instead. It seems to me that between the XZ-2, G15, the P7700 is 'probably' the most complete of the bunch while having a bit longer reach on the long end. $100 cheaper than Oly's, and I'm thinking that all of these camera's will offer similar qualities, and excellent images. However...

Do you have any idea whether the Olympus Viewfinder would work on the Nikon? I like the idea of a viewfinder and Nikon isn't offering anything for this yet. My research on this has turned up zilch, but what I did find was that the VF-2 is also 're-branded' and sold by Leica as their X2-EVF2, so I thought that maybe this would also work on other makes as well. Whatdaya think?
